{"product_id":"system-three-marine-spar-urethane-varnish","title":"Marine Spar Urethane Varnish","description":"\u003cp\u003eSystem Three® Spar Varnish is a urethane enhanced film finish formulated to protect against the harshest salt water and marine environments, as well as provide protection for your outdoor projects. It contains UV absorbers and other additives that help it combat the worst that nature has to offer. System Three Spar Varnish, like all outdoor film finishes, is more elastic and a bit softer to enable it to move with the wood as it expands and contracts with the seasons. It’s a good finish for outdoor furniture and projects in general but like all outdoor finishes, it could use a little help – a good base underneath to keep it looking good longer. We recommend sealing the wood underneath with a good waterproofing sealer.\u003cbr\u003e\u003cbr\u003eThe number one enemy of an outdoor film finish is moisture that gets into the wood and underneath the finish. Moisture makes its way into the wood via the wood actually breathing (a result of not sealing the wood off from ambient moisture in the air), as well as through micro fissures in the topcoat caused by temperature extremes and UV radiation. So, if you’re contemplating a film finish for your outdoor furniture – consider using a good sealer underneath. A sealer will combat this “breathing” the wood does and be a barrier to prevent moisture from expanding underneath the topcoat, even if it manages to get through the micro fissures. The bonus for this hard work is your finish will look good well beyond what you might otherwise expect…but not forever.\u003cbr\u003e\u003cbr\u003eStart with a good sealer such as System Three Clear Coat. If it’s going to be outside all the time all year long and even if it’s not, System Three recommends encapsulating the wood with System Three Clear Coat prior to assembly. This will effectively stop the wood from breathing and provide an excellent base for the topcoat to adhere to plus it will stop moisture from spreading underneath the finish through micro fissures. Be advised that even if you follow all these recommendations, you will still need to take steps to care for your project in the off-season and to eventually apply a new coat or two of finish or remove the old finish down to the Clear Coat and recoat the piece. However, following our suggestions will keep your Adirondack chair or other outdoor project looking good longer, and it will be easier to recoat when necessary.\u003cbr\u003e\u003cbr\u003e\u003cspan\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eDesigned for marine and exterior wood surfaces\u003c\/li\u003e\n\u003cli\u003eOffers excellent protection from salt air and water\u003c\/li\u003e\n\u003cli\u003eContains ultraviolet light absorbers that protect finish from exposure to sunlight\u003c\/li\u003e\n\u003cli\u003eFormulated to cure properly over System Three epoxy products\u003c\/li\u003e\n\u003cli\u003eDoes not require sanding between coats when additional coats are applied within 24 hours\u003c\/li\u003e\n\u003cli\u003eVOC compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Oil-modified urethane polymer\u003c\/li\u003e\n\u003cli\u003eSize: Quart\u003c\/li\u003e\n\u003cli\u003eSheen: Gloss\u003c\/li\u003e\n\u003cli\u003eColor: Very light amber\u003c\/li\u003e\n\u003cli\u003eInterior\/Exterior Use: designed for exterior use\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Directed at, but not limited to, the finishing and coating of wood\u003c\/li\u003e\n\u003cli\u003eApplication Method: brush, roll, spray\u003c\/li\u003e\n\u003cli\u003eCoats: varies per project (see PDF System Three Clear Finishing of Outdoor Wood)\u003c\/li\u003e\n\u003cli\u003eCoverage: 100-125 sq.ft.\u003c\/li\u003e\n\u003cli\u003eMinimum Application Temperature: 50°F\u003c\/li\u003e\n\u003cli\u003eMaximum Application Temperature: 95°F\u003c\/li\u003e\n\u003cli\u003eIdeal Drying Conditions: 77° F and 50% humidity\u003c\/li\u003e\n\u003cli\u003eDry Time - Tack Free: 4-6 hours\u003c\/li\u003e\n\u003cli\u003eDry Time - Dust Free: 8-12\u003c\/li\u003e\n\u003cli\u003eDry Time - Recoat: 12-24 hours\u003c\/li\u003e\n\u003cli\u003eDry Time - Complete Cure: 14 days\u003c\/li\u003e\n\u003cli\u003eClean-Up: mineral spirits or lacquer thinner\u003c\/li\u003e\n\u003cli\u003eMaterial VOC (g\/L) 440-450 g\/L\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e(1) Marine Spar Urethane Varnish - Gloss - Quart\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003ePlease see the PDF from System Three (link on this page) for more information on finishing outdoor wood.\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"System Three","offers":[{"title":"Satin \/ 1 Quart","offer_id":43405695352970,"sku":"847115","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Satin \/ 1 Gallon","offer_id":43405695320202,"sku":"847116","price":149.99,"currency_code":"USD","in_stock":true},{"title":"Gloss \/ 1 Quart","offer_id":43405695287434,"sku":"141904","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Gloss \/ 1 Gallon","offer_id":43405695254666,"sku":"841226","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0616\/1711\/1178\/files\/847115_000_001.jpg?v=1762272499","url":"https:\/\/www.woodcraft.com\/products\/system-three-marine-spar-urethane-varnish","provider":"Woodcraft","version":"1.0","type":"link"}
